We're dividing 45357840 by 998 
We want to figure out the number of times 45357840 can be divided by 998.

On to step 1:
998 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 998

Let's proceed to step 2:
45 divided by 998 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 998

Advancing to step 3:
453 divided by 998 is 0 with a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Grab the next digit (5) from the dividend, add it to 453, then carry on: 4535 / 998

Moving on to step 4:
998 goes into 4535 4 times with a remainder of 543.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3992 from 4535 to get 543.
Append the next digit (7) from the dividend to 543 and continue with: 5437 / 998

Advancing to step 5:
If we divide 5437 by 998, we get 5 and a remainder of 447.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 4990 away from 5437, we end up with 447.
Include the next digit (8) from the dividend after 447, then repeat: 4478 / 998

Let's proceed to step 6:
When dividing 4478 by 998, we get 4 with a remainder of 486.
Use 4 as the next digit of our solution. 
Result so far: 454.0
If we take 3992 away from 4478, we end up with 486.
Bring next digit (4) of the dividend behind the 486 and repeat the process: 4864 / 998

Going ahead to step 7:
When dividing 4864 by 998, we get 4 with a remainder of 872.
Write down 4 as next digit of the result. 
Result so far: 4544.0
The remainder is 872 after subtracting 3992 from 4864.
Include the next digit (0) from the dividend after 872, then repeat: 8720 / 998

Let's proceed to step 8:
The number 998 fits into 8720 8 times, leaving a remainder of 736.
The next digit of our result is 8. 
Result so far: 45448.0
Subtract 7984 from 8720 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 9:
7360 divided by 998 is 7 with a remainder of 374.
The next digit of our result is 7. 
Result so far: 45448.7
Subtracting 6986 from 7360 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 10:
The number 998 fits into 3740 3 times, leaving a remainder of 746.
Write down 3 as next digit of the result. 
Result so far: 45448.73
Subtracting 2994 from 3740 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Going ahead to step 11:
7460 divided by 998 is 7 with a remainder of 474.
Record the quotient 7 as the next digit in the result. 
Result so far: 45448.737
Deduct 6986 from 7460 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 12:
The number 998 fits into 4740 4 times, leaving a remainder of 748.
Write down 4 as next digit of the result. 
Result so far: 45448.7374
If we take 3992 away from 4740, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

On to step 13:
The number 998 fits into 7480 7 times, leaving a remainder of 494.
Write down 7 as next digit of the result. 
Result so far: 45448.73747
Subtract 6986 from 7480 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 14:
4940 divided by 998 is 4 with a remainder of 948.
Use 4 as the next digit of our solution. 
Result so far: 45448.737474
Deduct 3992 from 4940 and we're left with 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

Moving on to step 15:
If we divide 9480 by 998, we get 9 and a remainder of 498.
The number 9 becomes the next digit in our result. 
Result so far: 45448.7374749
The remainder is 498 after subtracting 8982 from 9480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 16:
4980 divided by 998 is 4 with a remainder of 988.
Write down 4 as next digit of the result. 
Result so far: 45448.73747494
Deduct 3992 from 4980 and we're left with 988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9880, and continue the process.

After the division, we end up with 45448.73747494 and a remainder of 9.88e-07.
